BlackBerry
Collaboration
Service
This setup type installs the BlackBerry Collaboration
Service, the BlackBerry Instant Messaging Connector, and
the BlackBerry Controller on a remote computer.
A remote BlackBerry Collaboration Service can support
multiple BlackBerry Enterprise Servers.
Your instant messaging environment can be IBM® Lotus®
Sametime®, Microsoft® Live Communications Server
2005™, or Novell® GroupWise® Messenger. Your choice is
not limited by your messaging server.
You can install only one type of the BlackBerry
Collaboration Service, and users can use only one type of
enterprise instant messaging application on the BlackBerry
device.
The BlackBerry Collaboration Service requires the following
persistent connections, based on your instant messaging
environment:
•If your instant messaging server is Microsoft Live
Communications Server 2005 and you are using
Transport Layer Security (TLS) as the communication
protocol, you require one persistent socket connection
for each instant messaging session.
•If your instant messaging server is Microsoft Live
Communications Server 2005 and you are using
Transmission Control Protocol (TCP) as the
communication protocol, you require three persistent
socket connections for each instant messaging session.
•If your instant messaging server is Microsoft Live
Communications Server 2005 and you are using
Hypertext Transfer Protocol over Secure Sockets Layer
(HTTPS) as the communication protocol, you require
three persistent socket connections to create one TCP
connection, and all instant messaging sessions use that
connection.
•If your instant messaging server is Sametime, you
require three persistent socket connections to create
one TCP connection, and all instant messaging sessions
use that connection.
•If your instant messaging server is GroupWise
Messenger, you require one persistent socket
connection for each instant messaging session.
Install the BlackBerry Collaboration Service on a remote
computer to maximize the number of available sockets.
